Q. In Williamson’s synthesis ethoxy ethane is prepared by
A) Passing ethanol over heated alumina
B) Heating sodium ethoxide with ethyl bromide
C) Treating ethyl alcohol with excess of $H_{2}SO_{4}$ at 430-440 K
D) Heating ethanol with dry $Ag_{2}O$
Explanation
(b)
$CH_{3}CH_{2}ONa + C_{2}H_{5}Br\underset{synthesis}{\overset{{Williamson}^{'}s\ \ \ \ }{\rightarrow}}CH_{3}CH_{2}OCH_{2}CH_{3} + NaBr$
